Hey guys, I've got a question. I'm wanting to replace the stock power supply in my Dell computer (which is only a 250 watt PS) with an Antec 480 watt PS and I'm wondering does anyone know whether or not this is possible? The reason is that I know that Dell uses a lot of proprietary parts (motherboards) and I'm hoping that they didn't change some wiring around so that you would have to get a PS from them. Thanks for the help in advance.

If anything, it will be a physical fit problem, not wiring. You may have to do, say, a little "modding" and tinkering around, but otherwise, you shouldn't have to do any complicated re-wiring or anything.

Many Dell's use a proprietary PSU & motherboard connector. What I recommend is opening up the case & taking a look at the connection to the motherboard. Usually it's a standard ATX connector, with an additional pigtail connection to another connector on the mobo. Many aftermarket PSU's provide this additional connector though, you'll just need to do a little homework

Dell's do / did use a proprietary PSU, You can't just look and see if it's got special connectors cause it looks like a regular ATX, it's just wired differently 12V where 5V would be on a normal PSU, etc. You can find some directions for modding a dell powersupply to work on a standard ATX MB here, it should be fairly straightforward from those on how to modify a standard ATX PSU to work on a Dell motherboard.
